How can I change my picture in the friends bar at the bottom of the screen
Depending which platform you are playing on
-if you play on the browser and you log with your profile picture that is on your forum you can change your avatar by going on your profile -> change avatar.
-If you are playing on FB then you change your picture from the fb profile
I hope this helps
siento la imagen con el texto en español pero no hay remedio, como puedes ver en la imagen al pinchar en "cambiar avatar" se te abre con la opcion de elegir uno de cualquier juego o la opcion de subir uno de tu ordenador ( uno propio ).
I feel the image with the text in Spanish but there is no remedy, as you can see in the image by clicking on "change avatar" it opens with the option to choose one of any game or the option to upload one of your computer (one of your own )
